Mechanical Systems Engineer I

Who we are:

Electra is reinventing ironmaking from the ground up with a breakthrough electrochemical technology that produces high purity clean iron and critical co-minerals. With two operating pilots in Boulder and a new demonstration facility underway in Jefferson County, we’re on track to reach commercial scale by the end of the decade. Backed by over $300 million and strategic partnerships with global leaders across mining, steel, and big tech, momentum is on our side. Recognized by Fast Company as a Most Innovative Company and a Next Big Thing in Tech, and named one of TIME’s 100 Climate Leaders, we’re building a company shaping the future of industry. If you’re looking to make an impact and join a team that’s driven, focused, and scaling, we want to hear from you.

What you will do:

The Mechanical Systems Engineer I supports the design, build, testing, and improvement of mechanical systems for Electra’s processing, material handling, and pilot or plant infrastructure. This is an early-career role focused on applying core mechanical engineering principles, producing quality technical work, collaborating across functions, and growing toward increased independence and ownership.

Responsibilities include:

• Support the design of mechanical systems, equipment skids, and plant infrastructure under the guidance of senior engineers.
• Develop and revise CAD models, drawings, layouts, and related engineering documentation.
• Assist with equipment and component selection using design inputs, vendor information, and internal standards.
• Support fabrication, assembly, integration, commissioning, and testing activities with technicians, contractors, and cross-functional teams.
• Troubleshoot mechanical systems and equipment with appropriate guidance and escalation.
• Document design decisions, test results, observations, and lessons learned clearly and accurately.
• Coordinate with process, automation, electrical, operations, and project teams to complete assigned work.
• Engage with internal customers and suppliers to gather inputs and to support execution.
• Follow engineering standards, templates, and document control requirements.
• Work safely and comply with all health, safety, environmental, and quality requirements.
• Actively build technical capability through feedback, training, and hands-on experience.
• Perform other duties as assigned.

What we need you to bring to the team:

• Bachelor’s degree in Mechanical Engineering, Electromechanical Engineering, or a closely related engineering discipline.
• 0–2 years of relevant experience in mechanical engineering, process equipment, manufacturing, pilot plants, or industrial systems.
• Foundational knowledge of mechanical engineering principles, including fluid systems, heat transfer, mechanical equipment, and system integration.
• Ability to apply engineering fundamentals to routine problems with guidance.
• Ability to document, communicate, and apply lessons learned from testing or project work.
• Ability to produce organized and accurate engineering work products, including models, drawings, calculations, and test records.
• Familiarity with CAD tools for 3D modeling and drawing development.
• Strong written and verbal communication skills and the ability to work effectively across teams.
• Ability to learn quickly, follow engineering standards, and manage assigned work within a defined scope.
• Willingness to support hands-on equipment builds, testing, and troubleshooting in lab, pilot, or plant environments.
• Proficiency with, or ability to quickly learn, Microsoft Office tools including Word, Excel, PowerPoint, Outlook, OneDrive, and SharePoint.
